kIIpmI Cast Iron and Sintered Compoment Unc°ated SUM B°R°N BN7000 Uncoated CBN grade for high-speed finishing of cast iron, powdered metals, and difficult-to-machine materials I General Features Medium-grain CBN sintered to a high density to achieve the maximum content percentage. Also delivers superior fracture resistance by increasing the binding strength between CBN particles. Provides stable, long tool life for high-speed finishing work with cast iron, powdered metals, and difficult-to-machine materials. Acid-treated CBN Sintered Body Structure BN7000 Holes made by the binder melting from the acid treatment. Few Holes Many Holes I Characteristics Excellent for high speed finishing of Cast Iron Good wear and fracture resistance in high speed machining of Grey Cast Iron. High efficiency machining of powdered metal With 4 different types of edge treatment, stable and long tool life can be achieved from machining of Sintered Alloys of any shape or hardness. Able to machine any Exotic Metals. Long tool life can also be achieved for the machining of exotic materials such as Roll, HSS and Heat-Resistive Alloy etc. I Cutting Performance Cast Iron Milling 0 500 1.000 1.500 2.000 Cutting Speed (m/min) Work material: GG25 (Pearlite) Insert (Cutter): SNEW 1203 ADTR, (FMU 4100 R) Cutting data: vc = 500 2.000 m/min, f = 0,2 mm/rev doc = 0,3 mm, Wet Turning of Powdered Metal BN7000 No chipping in any of the samples BN7000 able to continue Previous CBN Breakage Breakage Breakage l i i 50 75 100 Output (Times) Conventional Tool Breakage Work material: Sintered ferrous alloy, SMF4040 equivalent (HRB70, Interrupted Machining) Insert type: CNGA 120408 Cutting data: vc = 250 m/min, f = 0,1 mm/rev, doc = 0,3 mm, Wet 0 25 I Recommended Edge Treatment Cast Iron Turning ) Flank Wear Width (mm) O 1 N> £> O CO O - Previous CBN BN7000 O 20 40 60 80 Cutting Length (m) Work material: GG30 (Pearlite) Insert type: CNGA 120408 NU-2 Cutting data: vc = 800 m/min, f = 0,15 mm/rev, doc = 0,2 mm, Wet Interruption degree Negative Land a w r Standard 15° 0,12 No LF type - - No HS type 25° 0,12 Yes - Frequent W Round honed cutting edge L19 SUMIBORON
